  • Pipe thermally insulated by an elastomeric material and manufacturing method
    Patent number: 6615878
    Abstract: The present invention relates to a method intended for heat insulation of a pipe (1), comprising the following successive stages of depositing, on the outer surface of the pipe moving longitudinally, a thickness (3) of an insulating material made of elastomer having an elastic type behavior, substantially without irreversible plastic deformation, forming at least one circumferential slot (4) in the thickness of the material substantially orthogonally to the axis (2) of the pipe, and coating the insulating material thickness with a sealed sheath. In a variant, the slot is machined in the thickness of the insulant. The invention further relates to a heat-insulated pipe.

  • Optimized scraper for a conduit
    Patent number: 6574821
    Abstract: A two-directional scraping device (1;25) intended for a fluid carrying pipe includes at least one thin disk (6) made of polymer stiffened by reinforcing means (8) secured to the disk. The disk, including the reinforcement, is divided into petals by at least two radial slots (11) whose length is smaller than the radius of the disk, the radius of the disk being substantially greater than the inside diameter of said pipe.

  • Heat-insulated pipe and manufacturing method
    Patent number: 6530137
    Abstract: A method is intended for the thermal insulation of a flexible pipe. The method includes a first step of depositing a thickness of extrudable and rigid insulating material on an outer surface of the pipe, with the pipe moving longitudinally. The insulating material is cooled over a substantially rectilinear part downstream from the deposition area. Then, at least one circumferential slot is formed in the thickness of the rigid insulating material so as to restore flexibility of the pipe coated with the rigid insulating material. The thus-formed pipe includes a flexible inner pipe, a layer of rigid insulating material surrounding the flexible pipe, and at least one circumferential slot cut in the layer of rigid insulating material to allow flex of the heated insulated pipe.
